I have selected Subscribed as the default in my General settings:
When switching from my instance (feddit.de) to the Everything feed, I end up in Subscribed no matter which option I choose in the menu shown below. This is expected behaviour if I select Subscribed but not for Local or All. With pictures:
Choosing one of these
Also leads to this result
I used Subscribed as an example, but the same thing happens with Local or All as default, then Local or All will be shown respectively.
The weird thing is, it only happens switching from my instance, not if I was in one of the lemmy.world feeds or already in Everything (so selecting the intended option again a second time works, but I guess that's not how it's meant to work).
Absolutely, to my mind a community for an app is useful to discuss and give feedback on how you use the app individually, what could be better or different, etc. And then once you got consensus take it to GitHub and make an issue for an enhancement or an issue since that is how the developers over there keep track of these things.
Things that are obviously bugs can go straight to GitHub. But I get that not having an account over there is a hurdle.
